I have a question regarding the 2.9_r10183 trunk rel. When implementing
this ver. the layerSwitcher appears in the upper left-corner as opposed
to the upper-right (v2.8). It is positioned beneath the Navigation
Control. When the LayerControl is expanded the panel appears opaque and
the close handle is attached to the bottom outside corner. Because of
the opaqueness the handle can not been seen. I have not found a way to
alter this behavior in the css.
I'd appreciate any assistance. I am new to OpenLayers and hope this is
the appropriate forum to submit a question. If not please advise. Thnx.

I think that usability is important, for this I open the ticket
http://trac.openlayers.org/ticket/2567 to add the activation and
deactivation in Graticule control.

Hi Devs,
First of all, great work! It has been a pleasure to use the framework.
My app contains a vector based drilldown style map. United States
(labels: 2
char state abbreviation) -> State (labels: 2 char county abbreviation)
->
County (labels: 5 digit Zip code). The target browser is IE 7/8. While
it
renders fine on non-IE browsers, IE itself spends a significant amount
of
time drawing text according to the built-in profiling tool. I've tweaked
the
geometries to have max 2000 vertices but some levels contain over 200
features (extreme cases: 254 Texas counties, 282 Los Angeles zip codes).
I was thinking of preventing the label from being drawn if it does not
fit
within the width of the geometry at the centroid for the current zoom.
It
seems like some time is spent rendering the VML textbox offline to
determine
the size. I would be fine with estimating the width from the number of
characters since the label text characters are relatively equal width.
VML
rendering is beyond what my brain can wrap around so any suggestions of
how
I can tweak VML.js to do this?
Thanks!
-=Cliff

Digging deeper, as ugly as this is, it will work for me for now:
In OpenLayers.Renderer.drawFeature()
if ((bounds.getSize().w / this.getResolution()) > (style.label.length *
7))
{
this.drawText(feature.id, style, location);
} else {
this.removeText(feature.id);
}

Message-ID: <05e801cad6df$320993e0$22099...@us.ray.com>
Content-Type: text/plain; charset="us-ascii"
We are trying to optimize the performance of our app that uses
OpenLayers (IE 7&8). It appears that the node.style calls in the VML.js
are
taking a lot of time in certain cases and we were trying to use cssText
to
get it done in one call. Has anyone tried using one node.style.cssText
call
instead of multiple node.style calls?
Using node.style.cssText works one time when the data is first drawn
but
future changes to the node's cssText don't seem to take effect (ex: data
will be created in the correct location but the data never moves [top,
left]
when the user zooms).
Any ideas are greatly appreciated?

Hi list members,
I posted a message on 26 of March reporting a strange displacement that
only effects raster maps. I am pretty sure the WMS are alright, since
another client displays the maps correctly. Due to the pixel size, the
difference is big enough to become quite obvious.
The fact that GetFeaturteInfo always returns the right (expected) values
even if the pixel is not the one that should be visible at the
particular point, made me suggest that this could be a display artefact.
- ??
For more details and test code see my message on 26.3.2010
I received no hints so far. Should I file a bug?
Regards,
Stefanie

Hi list,
I would like to call for a vote on a second release candidate (RC2) for
OpenLayers 2.9.
4 tickets have been pulled up (2561, 2562, 2563 and 2564), I've verified
all tests still pass in IE6 and FF 3.6.2, so all is in good shape.
Best regards,
Bart
